With the release of their new self-titled album just two days prior, electronic music pioneers The Crystal Method took over the El Rey Theatre to celebrate the latest accomplishment in its impressive 20-year run.

Sporting a star-studded band consisting of former Guns N’ Roses guitarist Richard Fortus, former Nine Inch Nails bassist Danny Lohner and former Primus drummer Bryan “Brain” Mantia, Ken Jordan and Scott Kirkland made sure to do it up big for their hometown fans — and that meant having a few surprises up their sleeve, too.

With vocalists Dia Frampton, Franky Perez and Ryan Maginn making guest appearances over the course of the night, the two-time Grammy Award nominees pulled out all the stops to keep an older, yet passionate EDM crowd on its toes.

But in the end, there was no bigger surprise than when Filter frontman Richard Patrick stepped on stage for the show’s final song and belted out the lyrics to “Trip Like I Do,” the original version of the song he remixed with The Crystal Method way back in 1997.

Front and center, Josh Herwitt was there to catch all the action from the LA-based duo.
